Researchers at the Department of Energy’s Pacific Northwest National Laboratory – the same people who brought you millimeter wave scanners at TSA checkpoints – are developing a new scanner so you won’t have to take off your shoes at airport security.
This project blasts these same millimeter waves at your feet, cutting down on the shoe carnival for flyers who lack precheck and reducing the time in line for passengers that no longer have to take their shoes off and put them back on.
